LOOSE-LEAF-BOOK CONSTRUCTION.

Specification of Letters Patent. Patented; NOV. 14, 1911.

Application filed August 4, 1911. Serial No. 642,233.

To all whom it may concern:

Be it known that I, EDWARD W. HILL, a citizen of the United. States, and resident of New York, in the county of Queens and State of New York, have invented certain new and useful Improvements in Loose- Leaf-Book Construction, of which the following is a specification.

My invention relates particularly to a note book or tablet construction for separate leaves or sheets of paper for instance, note paper.

The object is to provide a simple and inexpensive construction, the parts of which can be readily and accurately assembled in manufacture and in which leaves or sheets 7 of paper can be readily inserted and securely held and yet from which they may be readily removed. In my former application #581,930 I have shown a somewhat similar construction.

It is the particular object of the invention claimed herein to simplify the former construction whereby the cost is reduced and the parts may be more readily and accuratplly assembled in manufacture andoperate In its preferred form the invention con-v desired to separate the parts to remove any of the sheets. The parts are so arranged and constructed that the clasps can be readily operated to release and separate the parts by holding the book with'both hands, the cover being raised and the thumbs inserted beneath the cover, the forefingers pressing upon the finger piecesof .the clasps and the remaining fingers being underneath the book. When the finger pieces are pressed,

' the catches are released and the thumbs and forefingers may then be utilized to lift the cover.

Figure 1, is a perspective VIGWShOWHIg I the operation of removing the cover. Fig.

2, is a perspective view (f a construction having a top bar or cover plate instead of a complete cover, the parts being separated. Fig. 3, is a'perspective view showin one of the clasps, the parts being connecte Fig. 4, is a perspective view sho' ving the parts of the clasps and holders'separated. Fig. 5, is an end view of the upper and lower portions with the parts of the clasps separated. Fig. 6, is a fragmentary detail sectional view showing one of the pairs of holding posts and clasps with the leaves; Fig. 7, is a plan view showing the method of alining one of the clasp parts with a pos1 and supporting bar. Fig. 8, is a perspecyive view of the parts of a clasp separated. Fig. 9, is a rear view showing the parts o? the clasp 0on nected. In the drawing 1 indicttes the base or back cover, 2 the top cover and 3 the perforated sheets or leaves consti .uting the filling.

4 and 5 indicate the clas s for connecting the parts together.

6 and 7 are the bottom and top bars respectively which constitut the supporting plates for the clasping and iolding means. I

8 and 9 are the telescopi 1g osts secured to the bars 6 and 7. Prei stably there are two pairs of these posts for holdin the paper. These posts prefer ably haveieads 10 and 11 respectively wl ich prevent the posts from pulling through, the bars.

12 and 13 are the arms of a clasp. A clasp is provided adjacent 1 ach ost. Preferably these clasps are form ad 0 sheet metal such for instance as spring brass so that they will be durable and el; .stic. They may of course be nickeled or otherwise plated. The two arms 12 and 13, W] ten the arts are together, overlapeach other as s own in Figs. 1, 3, 6 and 9. The an n 12 has a rearwa'rdly projecting shoulder 14 and the arm 13. has a shoulder 15. The tip of the arm 12 is preferably inclined outwardly as shown in Fig. 5 and the. shoulder 14 is formed by indenting the mt tal and forming an incline 17. The shoulde1 15 is formed by cutting the metal and forcing outwardly a portion 19 which leaves an 1 )pening beneath wider than the arm 12, th: edge 18 being inclined, downwardly somev hat as shown in' Fi 5. 1

'Ihe parts are adapted toi be connected by inserting the post 9 into th: tubular post 8 I of sheet metal as mentioned and the arm 12 has a base plate portion 20 bent at right angles and which fits over the edge of the bar 6. This plate portion also has lugs 21, 21 adapted to be positioned by the head 10 of the post 8 so that in assembling the parts in manufacture the clasp member with its spring arm 12 will be in the proper position relative to the post 8. When the plate 20 is in position on the bar 8, the parts are connected in a suitable manner as for instance by means of a rivet 22. In a similar manner the upper clasp member has a plate portion 23 with lugs 24, '24 positioned by the head 11 of the post 9 and is secured to the bar 7 by means of a rivet 25.

It will be noted that when the parts of the clasp are interengaged they are in the position of Figs. 6 and 9. By pressing inwardly on the projecting portion 19 the shoulder 15 may be disengaged from the shoulder 14. To permit this a space 26 is left between the ends of the leaves 3 and the parts of the clasp. The part 19 therefor constitutes an operating button or finger piece. When two clasps are employed as shown herein, which is the preferred form, the clasps may be readily released by e11- gagement of the forefingers as shown in Fig.

1 and the cover removed by the use of the thumbs and forefingers. In making the finished book, strips of cardboard 27 and 28 may be used underlying and overlying respectively the bars 6 and 7 and any suitable form of fabric such as 29 and 30 may be used to embellish or otherwise finish the book and its fittings.

The tip of the arm 12 is preferably considerably narrower than the opening beneath the finger piece or operating button 19 so as to allow for some variations in construction and assembling. By this construction where the operating button overlies the engaging shoulders both of the'clasps are the same, that is, there are no rights and lefts as would be the case if the operating button were located on one side or the other of the engaging shoulders. It is therefore possible to use the clasps interchangeably at the right or left of a book. Obviously these clasps may be made in different sizes. It will be noted however, that this binder is primarily inextensible andonly calculated to be used with a given thickness of paper. Obviously however, the exact number of leaves employed is unimportant.

What I claim is 1. In a loose leaf book construction, the combination of a base, two tubular posts carried thereby adjacent one edge, loose perforated leaves thereon, a cover, two posts carried thereby for telescoping with the tubular posts, a clasp member adjacent each post, each clasp member consisting of an elastic arm of sheet metal, opposite clasp members overlapping and provided with automatically interengaging abrupt shoulders, the members Whose shoulders fit behind the other shoulders being provided with projecting portions constituting buttons overlying the shoulders to receive the pressure of the fingers to disengage the shoulders while the base and cover are held so as to permit immediately subsequent separation of the parts substantially as shown and described.

2. In a loose leaf book construction, supporting plates, telescoping posts carried by said plates, clasp members arranged in pairs and having base plate portions secured to the supporting plates and with lugs positioned by said posts, said clasp members also havin spring arm portions bent at substantia ly right angles to the base plate portions and provided with automatically interengaging shoulders, one of the spring arm portions of each pair being provided with means for digital engagement for releasing the shoulders.

3. In a loose leaf book construction, supporting plates having perforations, headed telescopic posts carried by said plates and having their heads outside of said plates and their shanks extending through said perforations, and a pair of bent spring clasp members each having a base plate with lugs positioned by the heads of the posts, rivets for securing the base plates to the support ing plates adjacent the posts.

4. In a loose leaf book construction, a clasp comprising a spring arm having a backwardly directed shoulder and an outwardly rojecting finger piece with an opening etween the finger piece and the shoulder and a second arm adapted to slide into said opening and having a shoulder to automatically engage the first mentioned shoulder When the arms are brought into engagement.

5. In a loose leaf book construction, telescoping leaf supporting posts and elastic sheet metal clasp arms adapted to overlap each other adjacent the posts, one of said arms having a finger engaging portion with an opening beneath it and a shoulder behind it, the other arm being adapted to enter the opening and having a shoulder for aucally engaging the first m entioned shoulder when the arm has entered the opening and the posts are telescoped, tie relative length of the posts and arms beng such that the 15 posts begin to telescope bei ore the arms come into engagement.
